With the result in ecological disaster but I am very satisfied.
As Ringlight it works very well, but when lightning not likely.
The flash is only fired from the camera, but not controlled.
Therefore, man must first manually calibrate aperture and shutter speed.
So man is using the ring flash rather then as a ring light.
The results can, however, be proud!
The battery indicator blinks in the ring light mode to get the battery level correctly display must be switched to the flash mode.
The device appears to be identical to the Polaroid 48.
